TL;DR
This paper reports the first measurement of the total muon flux underground at the Sanford Underground Research Facility's Davis Campus using the Majorana Demonstrator veto system, providing a precise flux value at a significant underground depth.
Contribution
It presents the first underground muon flux measurement at the Davis Campus using the Majorana Demonstrator veto system in two configurations.
Findings
Measured muon flux: (5.31±0.17) x 10^-9 muons/s/cm^2
First underground muon flux measurement at this site
Demonstrated effectiveness of the veto system in flux measurement
Abstract
We report the first measurement of the total MUON flux underground at the Davis Campus of the Sanford Underground Research Facility at the 4850 ft level. Measurements were done with the Majorana Demonstrator veto system arranged in two different configurations. The measured total flux is (5.31+/-0.17) x 10^-9 muons/s/cm^2.
